The Robinson women and Smith must deal with dangers while the men are away.
The John Williams scored teaser is one of my favourite moments of Lost In Space: total disaster stations! Meteors are crashing down on the Robinson men with Smith back at the ship seeing trouble on the radar he says "I knew it, doomsday". Fade to black. Pure Irwin Allen stuff here!
Sadly, the rest of the hour fails to be as pleasing as the teaser but the well directed (by Sutton Roley) creature from the pit has it's moments.
Sadly, Smith has now turned into a clown, and he will remain like this, but there are still other things about the series to enjoy. And Smith still has other good things to do in the series as well.
